I don't disagree with your worries, but as is often pointed out on these forums, there are lots of problems inherent in placing qualifying restrictions on what is, at bottom, a group of rights. (I phrase it that way because there is a right enshrined in the Constitution as well as an even more basic human right to survival and protection of one's loved ones.)
When I see people struggle at the range and read reports like this about concerns at concealed carry classes, I try to remind myself that the people involved are at least trying to learn, and that they are at different spots on the learning curve. I was a beginner once - or at least I think I was, my memory is a bit foggy that far back. Maybe we are seeing the first steps towards a high level of expertise.
